ORLANDO, Fla. -- Detroit Tigers star Miguel Cabrera cut off all contact with his mistress and ended financial support for their two children after being given an ultimatum by his wife last spring, according to claims in a new court filing.

The arguments were made by Belkis Mariela Rodriguez in a court filing to support her bid for temporary child support Monday in Orange County Circuit Court.

The proceedings were closed to the public and the judge's ruling on the matter -- if he has made yet made one -- is unknown.

Rodriguez argued that the divorce filing by Cabrera's wife, Rosangel, prompted Cabrera to change his phone number and unilaterally end child support for his two children (age 5 and 2) by Rodriguez.

Cabrera's attorneys have not disputed that he is the father of the two children. Cabrera also has three children by his wife.

Rodriguez was seeking temporary child support of $20,000 per month, which she claims is the amount Cabrera was providing before he cut off contact.

"(Rodriguez) is not asking for some newly crafted sum of support based solely on imagined expenses in order to 'extort' unfounded amounts of money from (Cabrera), but, instead, is seeking for (Cabrera) to pay what he always paid and always promised to pay for his children, before unilaterally reducing this amount to pander to his wife," Rodriguez's attorney wrote in the court filing.

Temporary child support is an interim measure before a final agreement is reached. Rodriguez's attorneys argued that she is in dire financial straits as a result of being abandoned by Cabrera and is at risk of defaulting on the $1 million home that he helped her purchase.

"The additional several thousand dollars... that (Cabrera) historically paid means absolutely nothing to him, financially, whereas it makes all the difference in the world for (Rodriguez), who is now having to pick-and-choose between bills and expenses for the children," her lawyers wrote.

Rodriguez's attorneys noted that Cabrera makes $30 million per year and has "multiple mansions, each worth more than $3-$4 million."

He had previously paid for his two children by Rodriguez to take a European vacation and a Disney Cruise and also provided money for Christmas gifts, according to the filing.

Rodriguez said that although the children had brief visits with Cabrera in the past, they have not heard from their father since he cut off contact.

"These minor children should not be penalized because their Father's wife is angry that he chose to have a relationship with their Mother and otherwise support them over the years, as he rightfully should have done," Rodriguez's attorneys wrote.

Rosangel Cabrera has been present at two mediation hearings, the most recent of which was last month. Neither produced an out-of-court settlement.

"(Rodriguez) allowed (Rosangel Cabrera) to be present... as well as for (Cabrera) to communicate with his wife, even though she is not a party to this proceeding and has no legal right to be involved in this matter and, customarily, would be excluded, by law, from such settlement discussions," the filing said.

"I know he may tend to mess up off the field sometimes, and you read about it in these gossip magazines, but on the field, this guy is a professional," Tigers general manager Al Avila said. "He knows the game and he's got the pride where he wants to finish his career strong."
